Be it known that l. SAuUEL Y. WEI-ms, a citizen of the United States,residing at Highland Park, in the county of Chattanooga and State ofTennessee, have'inw'ented new and useful lmprovementsi nBlows. of whichthe following is a specifications "j The invention nelatesg'enerally toan improvement in disk plows, and particularly to means whereby theeffective operation of the cutting-disks may be adjustably controlled.at the will of the operator.

The main object of the present invention is the production of meanswhereby the plow may be adjusted to accurately regulate the width of thefurrow and, determine the.

' amount of cut-of the disks.

'Another object of the invention is the productionof means forpermitting the angular movement of the furrow-wheel with relation to theline of draft, whereby the plow is adapted for close turning at the endof the furrow.

Vlith these objects in View the invention consists in certain details ofconstruction and combinations of parts,which will be described positionoccupied after operation of the lever. to vertically adjust theplow-frame.

Fig. 4 is an end elevation illustratingthe osition of the parts afteroperation to alter the vertical inclinationfof the furrow-wheel.detailed perspective illustrating the construction in the connectionbet-ween the caster-wheel and plow-framel Fig. 6 is a perspectiveillustrating the forward furrowwheel connection, the parts being shownseparated.

Referring to the drawings, wherein like parts are designated by similarreference-numerals throughoiit the several views, my improved adjustingmeans are illustrated in connection with a rotary diskplow, including@/mainfplate 1, to which is secured intersaid main Fig. 5 is achangeable duplicate disk-beams 2, carrying arms 3. to which is securedthe disk'l. arms 3 are connected by rods 5, suitably controlled throughan adjusting-lever 6, mounted on the main plate.

So far as the novel features of the presentinvention are concerned nofurther detailed description of the plow structure is deemed necessaryherein, as such forms the subjectmatterof a copending application, filedFebru'ary 28, 1905, Serial No. 247,703. be understood, however, that lcontemplate the use of the novel features hereinafter described inconjunctionavith any plow structure for which they may be adapted.

'The main feature of the present invention resides in the connection ofthe furrow-wheel to the main plate of the plow structure,which is soconstructed as to permit adjustment of the furrow-wheel to vary thewidth of the furrow cut by the disks and also to permit independentmovement of the furrow-wheel to vary its lead. With this feature in viewthe main plate 1 of the plow structure is formed or provided adjacentthe furrow-wheel with a The It is to bearing or sleeve 7 projectinglaterally from' late. Vvithin the sleeve ismounted a spind e 8,terminally projecting beyond the sleeve and secured against longitudinalmovement therein by asuitable key 9. To the outer end of the spindle isconnected a rearwardly-extending arm 10, terminallysup porting avertically-arranged sleeve 11.

A spindle 12 is revolubly mounted within the sleeve 11, being heldtherein by a key 13.

The spindle is preferably enlarged at its lower end, as at 14, to bearagainst the lower end of the sleeve 11, and to said enlargementissecured or formed integral therewith a forwardly-projecting sleeve 15.The axle 16 for the furrow-wheel 17 ,is provided at its inner end with aforwardly-pro'ecting arm 18, arranged at right angles to tl e axle 16and being revolubly supported the sleeve 15, being held against longituinal movement therein by akey 19.

A lug 20 pro'ects forwardly from the arm 10, forming a red part of'saidarm, to the uhder side of which lug is pivotally connected a bar 21,projecting forwardly and terminally connected to,one end of a link '22,the opposite end of which is, connected to the free end of a lever 23.:24 represents aYs egnient-plate just the cutting dept arranged forcoiiperation with said lever and fixedly supported at the upper end of astubshaft 25, which extends downwardly through the plate 1 and securedtherehelow by a nut 26 in a manner to permit a revolution of said postin the operation of the parts. The lever,

which is provided with the usual dog 27 for engagement with the notchesin the segment 24, is pivotally supported near the lower end of saidsegment, whereby said lever, segment, and stub-shaft may be turned for apurpose hereinafter described.

The connection of the main frame of the plow with the furrow-wheelthrough the rev oluhle arrangement of the spindle 8 within the sleeve'i, in conjunction with the lever 23 and cooperating parts justdescribed, provides for the vertical adjustment of the main frame withrelation to the Wheel, as it is evident that throu h a vertical movementof, the handle end '0 the lever. the spindle 8 will be rocked in thesleeve 7, and as the outer end of said spindle has a fixed point ofsupport said rocking of the spindle will elevate or lower the frame withrelation to the wheel--that is, with relation to the oundwhereby to adhof the disk In the use of this feature of the invention with a disk plowhaving a single cutting-disk the direct rearwardly projection of thelever 23 will position its handle end convenient to the seat of theoperator; but when using two or more disks, as in a gang-plow, thenormal projection of the lever will osition its handle and remote fromthe seat of the operaton'and it is the purpose of the structuredescribed to practica ly meet this requirement. By loosening the nut 26the handle end of the lever may be swung into convenient relation to theseat of the operator, the movement of the forward end of the lever beingaccommodated throughthe medium of the arm :21, which is 20, projectingfrom the arm 10.

It will thus be seen that the lever may be adjusted to position itshandle end within convenient reach of the operator without regard to thenumber of disks used in the par-' ticular structure, whereby theoperator may readily control the cutting depth of said disks withoutleaving his seat. j The structure, including the sleeve 11, spindie 12,and sleeve 15, are arranged to rovide variation in the lead of thefurrow-w icel, as the revoluble movement of the spindle 1.: within thesleeve 11 will vary the angular re-- lation of the furrow-wheel to theline of drai' t. To insure the return of said wheel to the desirednormal position, I fixedly secure an arm 28tothe lugZO, said armprojecting laterally therefrom and bearing against a re 1 stop so,

formedon said lug. The outer or fre to?- rmnal-of the arm28 is connectedtonne Mm of ajcoiled spring 30, which extends wer is thus made foraccmnmodating'said wheel in turning the plow, the spring 30 operating toquickly return the wheel to normal position as the draft on the plow isreestablished. Under ordinary circumstances the set-screw is sopositioned to normally maintain the furrow-Wheel in the direct line ofdraft; but in some instances, as in plowing hilly land, it is desirablethat i. nrowwheel be given a lead l'romthe whereby to insure proper rnoplow, as is well understood. Under conditions the set-screw will headjus '1 limit the movement of, the "hirrow desired, insuring the properof s" when in normal position, it being that the i ring 30 operates toreturn row-whee to the normal osition. trolled by said set-screw, imrnerdirect draft on the plow is reestab- The structure, including. the sleforwardly projecting arm 18 of wheel a e, are arranged to permi in thevertical angle of the 1 whereby to regulate the furrow me n X. thedisks.

To manually control th the furrow -'wheel, staggering of the v.callyprojecting lever to 1 preferably projecting throng? the sleeve 15immediately continue ment 3], the lever being providm usual dog 35 forengagement with ilnotchi in said segment: By this construction the levermaybe moved toward or from the plow-- frame to rock the spindle 18 inthe eave 15 to give the furrow-wheel the desireejl amount of verticalinclination or stagger, the parts being locked in the desired positionthrough engagement of the lever-dog with the segments.

As the hirrow-wheel rides in the furrow and the next succeeding furrowwill be spaced therefrom a distance equal to the distance between saidfurrow-wheel and the first disk, it is evident that if said furrow-wheelhe in elined from the vertical to'vary the distance first disk thedistance of the'rarrow out by said disk from the furrow in Williill thewheel llS -1.1l1llg may be regulated. Furthermore,

of its bearing-point in the furrow from the in plowing siding land thetendency of the plow in the lower side hill is to slide toward theplowed landand in upper side hill to slide toward the unplow'ed land,both of which disadvantages may be readily corrected b v adjustin theinclination or sta ger of the furrow-w reel to the extent desire i Inconnection with the adjustment of the hirrow-wheel to vary the widthofout of the next adjacentdisk of the plow it has been found necessary torovide a similar adjust; ment for the last dis of the gang.

To rovidefor this adjustment, I secure on the hock 36, which forms partof the structure of the copending application referred to and isadjustable to control the height of the plow frame from the ground, arearwardlyextending sleeve 37, to which is fixed a vertically-projectingsegment 38. The axle 39 of the caster-wheel l is provided with a for-'wardlyprojecting arm ll, arran ed at right angles to the axle 39 andrevolub v seated in thesleeve being suitably keyed against longitudinalmovement. A lever -12 is secured to the arm ll, projecting through anopening in the sleeve 3?, immediately contiguous the segment said leverhaving the ordinary dog -l3 to cooperate with sail segment. Operation ofthe lever will alter the vertical inclination or stagger of thecasterwhcel with the ellect to vary the cutting distance of the lastdisk of the gang in an obvious manner.

it is understood. of course. that, as usual in plow construction, thecaster-wheel is nor mally arranged at a vertical inclination to offsetthe draw oi the (llSliS and that the IQtLHS described for manuallyvarting the inclination or stagger provides for elliciently controllingthe width of cut of the last disk of the gan ly vii toe of theconstructions and arrangeunr-nt of parts as above described it will benoted that 1 am enabled to control the cutting depth of the disks byoperation of the lever 23 and that said lever may be adjusted lot.convenient manipulation by the operator whether the Slow carries one,two, or more disks: that the furrow-wheel is adapted for free andindependent castering in a rearward direction to permit rcadvturning ofthe plow, returning to normal position underthc influence of a spring,the casteringof the wheel in a forward direction being limited by'an adjustable means whereby to control the lead of the wheel as may bedesired: that the vert-tcal inclination or stagger of the furrow-wheelmay be adjusted to absolutely control the furrow width cut by theadjacent disk, and that the rear caster-wheel may be suitably adjustedto vary its vertical inclination or stagger to control the cutting widthof the T last dish of the gang. 7

in the various ad ustments described the parts are relatively arrangedthrough the 0;:-

eration of a single lever, the osition of the arts being absolutelycontrol ed and locked i in an adjusted position.

While I have shown and described the invent-ion as applied to a diskgang-plow of peculiar construction, it is evident that it is ei uallyapplicable to a single disk or other p It will be noted that theadjustments hereinbefore described are arranged for control ters Patent,is
